Why Do They Use Paper Straws in Plastic Cups?

The shift towards eco-friendly alternatives has been a significant trend in recent years, particularly in the beverage industry. One such trend is the use of paper straws in plastic cups, which aims to address environmental concerns while maintaining usability. Letu2019s delve into the reasons behind this choice and explore the broader issues of total waste and specific kinds of waste.

Total Waste vs. Specific Kinds of Waste: A Closer Look

The debate often revolves around the total amount of waste versus the specific types of waste. In the context of plastic straws and cups, both materials present unique challenges. According to biodegradable plastic standards, almost all materials are biodegradable; however, the time it takes for them to break down and whether they pose an environmental threat are crucial considerations.

In the United States, plastics can be classified as biodegradable if 90% of the material is fully mineralized into CO2 within 180 days. Unfortunately, this type of plastic is limited in its applications. Biodegradable plastic can only be used to make cups and grocery bags, given its strength requirements.

Key takeaway: Not all plastics are the same, and their biodegradability and strength make a significant difference in their usability.

Addressing the Dual Issues

Two primary issues need to be addressed when considering the use of paper straws and plastic cups: total waste and specific kinds of waste. Historically, multi-pack beverage containers faced similar challenges. Here are the older and newer designs for soda and beer:

The primary problem with the old design was:

Reason for the change: The new design uses more plastic but has several advantages:

It is made from recycled materials. It is reusable and recyclable.

While plastic straws face recycling challenges, plastic cups and caps, although rarely recycled, can be recycled if provided with proper receptacles. The bigger issue lies in their shape and people's disposal habits, which can harm wildlife.

The Environmental Impact of Straws vs. Cups

Theoretical vs. Practical Recycling: In theory, plastic cups are recyclable, but plastic straws are often discouraged in many recycling facilities due to issues with machinery. In practice, most places do not provide the necessary receptacles, making recycling a moot point.

Green initiatives, such as the zoo we work for, aim to reduce environmental impact:

Compostable plastic cups and lids made from corn were once used but were expensive. Switched to paper cups without lids or straws, though inconvenient, were preferred.

Alternative solutions, such as reusable metal and plastic straws branded with the zoo name, have been introduced.

Conclusion: The use of paper straws in plastic cups represents a step towards sustainability, balancing environmental concerns with practical usability. By understanding the differences in biodegradability and the specific challenges faced by plastics, we can make informed choices that positively impact the environment.
